OSCE Minsk Group French Co-chair welcomed Yerevan and Baku's positive assessments of the presidential meeting in Zurich.

"We held productive meetings in Stepanakert with President Bako Sahakyan and representatives of non-governmental organizations. Talks in Baku and Yerevan also proved efficient. Now we are planning to return to Baku to meet with President Ilham Aliyev and Foreign Minister Elmar Mammadyarov. I am hopeful we will succeed in arranging a presidential meeting within the coming months," Ambassador Bernard Fassier told a news conference in Yerevan on Tuesday.

At that he noted that Azerbaijan's ongoing attempts to discredit Armenia in the UN hamper the process badly.

The mediators also emphasized that the issue of Armenian and Azeri refugees is on the agenda as one of the key elements of the negotiation process.

Touching on NKR participation in talks, Ambassador Fassier said that Nagorno Karabakh will be engaged in the process one day.

"We always visit Stepanakert after meetings in Baku and Yerevan. But inclusion of Karabakh into talks depends on the parties to conflict," he said.

For his part, Russian Co-chair Yuri Merzlyakov that the incident which took place during the recent OSCE monitoring will be discussed at the OSCE Permanent Council's meeting on March 5.

"We expect the council to support the statement Ambassador Andrzej Kasprzyk will submit in Vienna," he said.
